I have added a button to my form from code because I'm linking a screen from other form, and in the linked form I've to add a back button. Now I success added a button in my form, but I cant handle the btnBack.Click
Dim btnBack As New Button
Dim y As Integer = 340
Dim x As Integer = 20
btnBack.Text = "Back"
[code].....
I how how to add a handle ex. with a button "AddHandler CType(obj, Button).Click, AddressOf Button_Clicked", but Button has an event called click. I have a control for which I would like to create an event called MoveUp, which is triggered when a button is clicked.
View 2 RepliesI had created a form(MDI Child) which have 3 to 4 dataset on it. They all are loaded from the database at the form load event and therefore takes too much time to load and show some part of form during that time. When it load completely it shows the whole form. Is there any way that user will see the complete form instead of some broken form.
View 4 RepliesI have 50 pictureboxes in one form. I need to write the same code for each one.one is to write a function for each PictureBox handling each object induvidually two is to write a function for all PictureBoxes that handle ALL object, but I have to declare each object in the Handles syntax of the subrutine as follows:
Private Sub PreviewTile(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PB1.DoubleClick, PB2.DoubleClick, PBChapel.DoubleClick
DrawBorder(sender, Color.Wheat, 3)
[code]....
I was wondering if there is a way to write a subrutine that will Handle ALL Pictureboxes without having to enumerate them.example
Private Sub PreviewTile(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.PictureBoxes.DoubleClick '<-- made up
DrawBorder(sender, Color.Wheat, 3)

View 2 RepliesI have an event in a module, like this:
vb.net
Module Module1 Public Event Event1(Value as Boolean)End Module
I want to be able to handle this event from different forms. This is what I tried to do...
vb.net
Public Class Form1 Private Sub Event1Handler(Value As Boolean) Handles WindowsApplication1.Event1 End SubEnd Class
But I get a squiggly line under WindowsApplication1 that says Handles clause requires a WithEvents variable defined in the containing type or one of its base types. I tried to swap Module1 in, but same thing. I tried without anything in front of Event1, but still nothing.
well my mouse has four buttons- can I handle the forth (Right Left Center and Forth) to do sumthing?
View 1 RepliesI have a Toolstripmenu with ten drop-down items in it.(named menu1, menu2, menu3 etc)
I have a sub with ten handles Menu1.click, Menu2.click etc.So clicking on any of the ten menu items calls the sub.But- how do I find out which one of the menu items was clicked?
I want basically:
foo = clickedmenuitem.text
I could do it with ten different subs but that would be a lot more code.Especially since the sub is quite large and I only need to know which item was clicked for a small part of it.
How do I find which of the ten handles for the sub was triggered?I tried handle.tostring but that gave the same string of numbers for each menuitem, that was clearly the wrong command.
I have a problem whereby some rubbish code is not releasing its memory (eventually reaches the 10k handle limit and crashes).I'm looking to insert some logging in the application to dump a list of handles present at the point of failure.
View 1 RepliesI have defined 5 variables T1, T2, T3, T4, T5 As Double and set them all = 0. On a form I have a enter information button. Each time the button is pressed I want to assign a different variable, to a text box input. For instance, If I enter 1 that will become T1, and then if I enter 2 and press the button again, that value becomes T2.
I have tried
If T1 = 0 then
T1 = textbox.text
End if
If T1<>0 And T2 = 0 then
T2 = textbox.text
End if
I have tried to use 'else' statements and all kinds of things like that to no avail. I can get the first two variables correctly assigned but three is impossible with my current understanding. Is there a way to do this, or do I need 5 buttons, so that I can control which variable is assigned? To be correct my intent is to create an observation with three variables each time the button is pressed.
For example, the first button press will result in three variables being assigned a value other than 0; they are T1, B1, and R1. I have just begun to understand the concept of arrays and am wondering if that may be the way to go in this situation. I was just going at this in a newbie way I'm sure and trying to handle each variable type individually, and figure out all the T* variables and move onto the B* variables.
I have this code in ButtonClick Handle event but nothing works :/ I was wondering why... I tried msg("") as well as the first line in the code to see if it works but nothing!

I want to achieve the following:
The user drags text from any open window not related to my application ( like firefox or word, for example) onto button1 on form1 in my application. when he/she does that, a new form (called form2 that contains a richtextbox) will open and the dragged text is directly copied (or inserted) into the richtextbox of the new form. button1 has allowdrop set to true. Beyond that I don't know how to proceed.
I tried:
e.effects = DragDropEffects.Copy
But it seems it is not enough.
I have a form for which the form load event only fires one time. When the program starts. It will not fire again until I end the program and restart. I have tried .show and .showdialog, but it acts the same. I have read about form load events loosing the handles, but my code looks exactly like it should.
Here is the load event code
PrivateSub frmBilling_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
LoadClients()
LoadTherapists()
LoadCPT() EndSub
Here is the code that calles the form.
PrivateSub BillingToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BillingToolStripMenuItem.ClickfrmBilling.Show()
frmbilling.show()
EndSub
I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.
